Java Task 1 Create an object of type FitnessExperiment that stores an array of StepsFitnessTracker, DistanceFitnessTracker, and HeartRateFitnessTracker objects. You could use code such as the following to initialise the array containing the fitness tracker measurements: FitnessTracker[] trackers = { new StepsFitnessTracker("steps", new Steps(230)), new StepsFitnessTracker("steps2", new Steps(150)), new StepsFitnessTracker("steps2", new Steps(150)), new HeartRateFitnessTracker("hr", new HeartRate(80)), new HeartRateFitnessTracker("hr", new HeartRate(80)) }; In the FitnessExperiment class, complete the implementation of the methods named getTotalSteps()and printExperimentDetails(). The comments in the code specify how they should operate and provide you with additional hints to get you started. You can use the method getSteps()in StepsFitnessTracker, but think how you will know the real type of each object in the array of fitness trackers (trackers in the example above). FitnessTracker…
